Bronze figurine of a bull-calf with silver plating found in a temple deposit at Ashkelon, in Canaan, ca. first half of 2nd millenium BCE. The text accompanying the photo notes:
"Literary sources reveal that the bull and calf were attributes of El and Baal, the chief gods of the Ugaritic pantheons..."

Note that Ashkelon WAS NOT a Philistine city ca. 2000-1500 BCE. The Philistines arrived ca. 1174 BCE and destroyed Ashkelon (later rebuilding it), dispossessing the native Canaanites of their lands. I have argued that the Golden Calf is not an Egyptian phenomena so much as a Canaanite god, it being a form of Baal-Hadad and of Yahweh (Hebrew: Egel-yah, "bull-calf Yah"). Yahweh was also called Baal according to Hosea 2:16. I suspect, along with other scholars, that Yahweh absorbed the epithets and characteristics of the Canaanite gods Bull-El and Baal-Hadad. In erecting a Golden Calf in Yahweh's temples at Dan and Bethel, Jeroboam was merely honoring Yahweh as Egeliah, "the bull-calf iah" (as in Hezekiah).
